Member for timber products

Abstract

[Problem] To enable fixation between members by fitting and provide a member for timber product in which joining with more flexibility is achieved. [Means for Resolution] In a sort of square timber having a predetermined shape and a given length, a groove 12 in the longitudinal direction and having a substantially concave shape in lateral cross section is provided and the width of the groove 12 and the thickness of the member in the direction of the depth of the groove 12 are a constant value A, so that fixation and fixing are achieved by fitting a member 11 to the groove 12 on the other member 11.

1 . A member for timber products which is a sort of square timber having a predetermined shape and a given length comprising: a groove in the longitudinal direction and having a substantially concave shape in lateral cross section, wherein the width of the groove and the thickness in the direction of the depth of the member are a constant value so that fixation and fixing are achieved by fitting a member to the groove on the other member.  
   
   
       2 . A member for timber products according to  claim 1 , wherein the dimension from the edge of the groove to the side edge of the member is a constant value or half the constant value.  
   
   
       3 . A member for timber products according to  claim 1 , wherein the depth of the groove is half the constant value.  
   
   
       4 . A member for timber products according to  claim 1 , wherein the dimension from one side edge to the other side edge of the member is three times the constant value, and the groove is positioned at the center of the member.
